Beit known that I, Lorman, H. WA'r'rnns, a citizen of the United State?, residing at Providence, in the county of Prbvidence and State of Rhode Island, have invented certain new and useful Improvements in Sparking following is a speciiica-g Fig. 9, a side elevation of an engine provide with my device.

Like characters of reference indicate like parts throughout the views. Y

My device is adapted for `useV upon both ftwo cycle and four cycle engines and is herein illustrated as applied to a two` cycle engine of standard construction, the details of which are therefore omitted.

The outer end of the c e by a artial revolution of the tlielug is centrally bored to form a longitucrank s aft and without complete compresdm chamber, 10, extending artiall sion of the charge. The inner en of the through the plug. chaini yer is of lessened diameter formin auxiliary chamber or pocket, 11, and a eveled shoulder .or valve seat, 12. Two paso sages, 13, 13, m the plug extend from o iposite sides'of the chamber, 10, to the com ustion chamber. Y a

Mounted in the chamber, 10, is a piston, 19, providedupon its face with the stein, 2 0, of a valve, 2l. A connecting rod, 22, connects the piston with a crank pin, 23, upon a crank arm or disk, r24, fixed to the armature, 25, of an electric generator supported by a bracket or arm, 26, mounted upon the To vthe above venumerated and other en ds, my invention consists of means for operating the magneto with the ohar compressed in the 4engine c linder, and ol t e driving mechmism emp eyed 4to thus operate same; of means .for insuring a circulation around the electrodes in the ex lesion chamber and within the area of the' eed fuel stratum' and of means positive and independent of the magneto drivingmeans for starting. the mag neto armature.

.. Upon the margin ofthe upper face of the below tie bearing,

, which rests against cam 3.

.to the outer end of the electrode, 16.

crank arm or disk 24 .is a lug ortprojeeton, ilerer. d The-arniatiire, piston, and valve 34,',contacting with the free en lever, 36, stationary intermediate its leigth ivoted to the end of the leven-36, is a rod, 38, slidably mounted in a post, 39, upon the end of the plug. Upon the end of the rod, 3S, is an adjusting nut, 40, against which abuts a spring, 4l, whose opposite end presses against the est, 39.

Fixed to t e base, 28, of the magneto is a step or bearing arm, 42, for the lower end of the armature, 25. To the armature is fixed an arm, 43, whose free end is connected by a link, 44, to the upper arm, 45, of a bell crank lever, 46, mounted upon a stud, 47, in the engine easing, and to Whose lower arm, 48, is pivoted the up er section, 49,Vl oi a telescoping cam rod. `his section has a longitudinal bore, 50, to receive as a sliding tit the upper end of a second section, 5l, mounted in a bearing, 52, upon the engine casing. Fixed upon the sections, 49 and 51, near their teloscoping ends, are collars, 53 and 54, respectively, against which press a spiral s ring, 55. The rod section,51, has 52, a shoulder,"56, and carries'upon its end the usual cam roll, 57,

upon the cam rod section, 51, presses against the bearing, 52,'and shoulders, 56, to keep the roll, 57, in Contact with the cam. lt will be understood that the described mechanism for communicating motion from the cam, 3, to the armature, 25, is not exclusive. i

The operation of the apparatus is as follows: When the engine crank has passed its center the cani, 3, starts the armature, 25, through the cam rodv connections, and through the crank disk, 24, andco-nnecting rod, 22, elevates the piston, 19,and the valve, 2l, slightly from the seat, 12, of the latter. At this instant, the compression of the engine Charge in the combustion chamber has reached its highest oint, and traversing the passages, 13, stri es the inner faces of valve, 2l, and piston, 19, with great force, imparting through crank disk, 24, a movenient at a high rate of speed to the armature, 25. The described impulse is pur iosed to rotate the crank disk approximately thirty degrees. The limit of this movement may be re ulated by the spring, ll1, which is adjustale by nut, 40. The advance of the crank disk through projections, 34 and 35,

imparts to the movable electrode, 16, aI Inovlenient whereby the contact-arm, i

rotary 17, is swim" away from the` electrode, 14, with great ibrce and in a long? arc thereby producing along spark f-teP-'fthe ex losion, the Contact arm,v17, is swung back into close contact with the electrode, '14,V by the action of spring, 41, upon the The spring, 5S,

rod, 38, and l l are forced back into original position by the cani, 3, rod 51 lever 46,? link 44, andarni l 43. rllie reservoir or pocket, 11, facilitates F the action of the Valve. l lt will be observed that the diameter of l thevalve, 21, is less than that ol" the piston, l 19, and that the inlet passages, 13, when the l valve is seated, open intermediate the piston and valve. Thereore, the balancing is so perfect that aftei'tlre latter is slightly raised trom its seat, *brit little pressure through the inlets is required to propel the piston, 19, and little mechanical force is required to initially unseat the valve. This initial unscating may be efl'ected at any time by manually depressing the cani rod section, 49, against the tension of spring, 55, which normally holds the valve, 2l, in its seat. The possibility of thus manually raising the valve from its seat by the exertion of very little force makes it possible to produce the spark and start the engine without completely rotating the crank shaft or coinpletelycoin ressiiig the charge. That is to say, the ily w ieel is rotated rear-A wardly a fraction of a rotation which pro.- ducesa partial compression, and the valve is next manually unseated asdcscribed. The-passage of. the charge from the com bustion chamber through the passage, 13, insures a circulation around the sparking points and prevents the development oi' a dead l'uel stratum around the electrodes. The cer tainty and strength of the spark is increased because of the great s eed imparted to the magneto armature byV t ie compressed charge. lor the pur oses 'of this invention, it is iininaterial whetliier the engine with which my i igniter is used is of the explosive or internal combustion type; whether the fuel is injccted into the charge before the engine crank has assed its upper center or after; or whet ier compressed charge consists oi fuel, or air, or fuel and nir inlxred.
